BARREL-TAP.

SPEGIFICATION forming part of Letters Patent N 0. 732,122, dated June 30, 1903. Application filed June 7 1901. Serial No. 63,654. (No model) To (tZZ whmit it nutylconccrn:

Be it known that I, ADOLPH SCHNEIDER, a

citizen of the United States, residing at Trini-' dad, in the county of Las Animas, State of Colorado, have invented new and useful Improvementsin Barrel-Taps, of which the following is a specification.

The invention relates, primarily, to barreltaps more, particularly intended for use in drawing or transferring efliervescing liquid, such as beer, from one receptacle to another, but which can also be used for drafting liquids.

The objects of the invention are to construct a barrel-tap which can be readily applied to or removed from a receptacle without any great inconvenience or trouble and which when applied to a receptacle will enable the liquid contained in the receptacle to be drawn therefrom without liability of waste, to effectually pr I'll; leakage in applying the tap to the recepluc-le, to enable air orother fluid pres sure to be applied to the receptacle as theliquid is withdrawn therefrom without change in the tap, thereby maintaining the requisite amount'of pressure in a receptacle for properly transferring the liquid under a predetermined pressure, to simplify the construction and improve the operation of barrel-taps, and to construct a barrel-tap which as a Whole will'be very compact, easily applied, and effective and reliable in use.

The invention consists in the features of construction and the combinations of parts hereinafter described and claimed.

' In the drawings, Figure 1 is a side elevacarrying the eduction-tube and showing the cork or stopper for the bushing inserted therein, and Fig. 3 an elevation showing a modification of the delivery spout or nipple of the eduction-tube.

The receptacle may be a cask, barrel, keg,

or other retainer for liquids which havea head or end A and a head or end B, fragments of which are shown in Fig. l. The tap is constructed with a bushing 0, adapted to be entered 'into the receptacle at a point suitable for the purpose. This bushing, as shown, has an exterior screw-thread for entering it into the wall or head of the receptacle and has an extension or prolongation constituting a bottom 0 for the chamber of the bushing, and this bottom has a central hole therethrough for the reception of the cork or stopper and for the passage of the eduction-tube in applying the tap to the receptacle, and, as shown, the interiorof the wall of the bushing has a screw-thread of coarse spirals. An eduction-tube D of a diameter and length required passes through the hole 'in the bottomG of the bushing when the tap is applied to the receptacle for use. This eduction-tube D in the construction shown has a passageway E for the liquid, and the outer or discharge end of the tube is attached to or connected with the shell or casing of a controlling-valve F, theplug of which valve has therein a passage which can be brought into communication with the pas sage-Way or channel of the eduction-tube for the outflow of the liquid in being transferred from one receptacle to another or otherwise. The'eduction-tube D has located therein a tube G, having a passage therethrough which at one end communicates with a passage in a nipple [-1, formed at its extreme end, for the attachment of a hose by means of which air or other fluid under pressure may be admitted to the receptacle, for which purpose the passage or chan nel in the tube G leads through the wall of the eduction-tube by a port I, which opens just below the end ofthe bottom of the bushing C, so that when theeductiontube is entered into thereceptacle through the bottom of the bushing the portI will dis charge pressure into the receptacle to act on the liquid contained in the receptacle and maintain the requisite pressure on the liquid as the liquid is lowered in withdrawal from the receptacle. The passage-way or channel for the liquid in the elluction-tubeD communicates by a port or ports J, leading through the wall of the tube at the lower end, so that liquid can flow from the interior of the recepmole through the port or ports J into the pasglasses or vessels.

A plug L, having an exterior screw-thread corresponding to the interior screw-thread of the bushing G for entering the plug into the bushing, carries the eduction-tube D, which tube passes through a hole in the plug, and in a stem extending from the plug and, as shown, the upper end of thestem abuts againsta shoulder or fiat face on the wall of the eductiontube to limit the entering of the tube into th attaching-plugandits stem. Attheupperend of the stem of the attaching-plug are arms or handles L, by means of which the plug can be screwed into the chamber of the bushing, and entered into an annular socket or opening L in the end face of the plugisa gasket or packing M, made of any suitable material, preferably of rubber, which as the plug is advanced into the chamber of the bushing will be compressed by the advance and impinge closely around the eduction-tube and against the face of the bottom of the bushing, making an air and fluid tight joint between the eduction-tube and the bushing against the escape of pressure. The entering of the plug into the chamber of the bushing attaches the eduction-tube in place and at the same time compresses the gasket or packing M, so that the plug serves both as a support for the educlion-tube, holding the tube in place, and also as a means for compressing the gasket or packing around the ed uction tube in the chamberof the bushing. The hole in the bottom of the bushing when the receptacle is filled is closed by a stopper or cork N, driven into the hole by any suitable means before filling the receptacle.

The bushing O is to be screwed into the head or wall of the receptacle, and the cork or stopper N is to be driven or forced into the hole in the bottom 0 of the bushing, so that the receptacle can be filled with the liquid. After the receptacle is filled and to withdraw the liquid therefrom and transfer the liquid to another receptacle or receptacles the plug, with the packing or gasket M carried in its end face, is screwed lightly into the chamber of the bushing. The eduction or tap tube D is inserted into and through the plug L and its stem and the packing until the end of the stem contacts the cork or stopper in the bottom of the bushing. The plug L is then advanced into the chamber of the bushing until the packing or gasket is compressed around the eduction or tap tube to make an absolute tight joint between the tap-tube and the bushing, which will prevent the escape of any liquid when the ed notion-tube is driven in, forcing the cork or stopper out of the hole or opening in the bottom of the bushing. The tap or eduction tube as it is driven in removes the cork or stopper by forcing it from, the hole or opening, and with such removal if the packing or gasket were not tightly compressed around the tube and against the bottom of the chamber in the bushing the liquid would fiy out or escape with the removal of the cork or stopper. The tap-tube is entered into the receptacle until its lower or inner end reaches the bottom of the receptacle or such position in the receptacle as may be desired for withdrawing the liquid, and if after the tap or eduction tube is fully entered any leakage is discovered around the tube and the bottom of the bushing an advance of the plug will further compress the packing or gasket and stop the leakage, making the tap as a whole positively liquid-tight, by which liquids of an effervescing nature can be withdrawn from a receptacle without waste. The withdrawal of the liquid from the receptacle reduces the pressure within the receptacle, thereby-interfering with the efficiency of the device in transferring the liquid from one receptacle to another, and to compensate for any reduction in pressure and maintain an equilibrium in pressure for withdrawing the liquid air or other fluid under pressure can be forced into 'the receptacle through the passage-way or channel of the tube or conduit G, the pressure entering through the nipple H and discharging through the port- I into the receptacle to act on the contents of the receptacle.

It will be undestood that a bushing is to be entered into the head or wall of each receptacle and when entered is to have the hole in its bottom plugged or closed by a suitable cork or stopper, so that every receptacle with. which the tapas a whole is to be used is provided with a bushing adapted to receive the plug carrying the tap or eductiontube. The tap or eduction tube can be removed from a receptacle after the contents have been withdrawn therefrom by simply turning backward the plug, permitting the removal of the eduction-tube with the plug when the plug is detached from the bushing. The detachable plug, with its eduction-tube, can be applied to another receptacle by entering the plug into the chamber of the bushing of the receptacle and compressing by thejadvance of the plug in the chamber the packing or gasket around the tap or eduction. tube, as already described, making a tight joint for driving out the cork or stopper as the eduction-tube is forced into the receptacle and into position for withdrawing the liquid from the receptacie, as already described. It will thus be seen that the detachable plug and its tap or eduction tube can be used with receptacles supplied with the attaching bushing, it only being necessary to detach; the plug and its tube from one receptacle and applythe plug and tube to another receptacle. The tap as a whole of the invention insures the withdrawing of the liquid Without any leakage or waste in applying the tap to a receptacle, and by reason of the separate passageways or channels for the liquid and pressure the admission of pressure does not interfere with the withdrawal of the liquid. The liq uid will flow through the eduction-tube and into the coupling and hose attached thereto leading to another receptacle when the plug of the valve F is properly turned to have communication through the plug between the tap or eduction tube and the coupling, and in inserting the plug and the eduction-tube into a receptacle the plug of the valve is to be turned, so as to close or shut off communication from the eduction or tap tube.

The construction shown in Fig. 3 for drafting liquid from a receptacle into a glass or vessel for use has the tap or eduction tube shorter than is required for such tube in transferring liquid from one receptacle to another, as in the construction of Fig. l,and a short taptube is enabled to be used, for the reason that the receptacle,especially a beer barrel or keg, is usually lying upon its side when tapped and. is tapped at the lowest point in its head for the contents to run out, and it is not necessary, therefore, that the eduction-tube should extend to the bottom or lower side or opposite head of the barrel, as required with a cask, barrel, or keg standing on one head, which is the usual position in filling bottles or other receptacles. The tube or conduit G for the pressure is shown in dotted lines in Fig. 3 and does not terminate in a coupling, as in Fig. 1, and with this arrangement a passage is formed in the plug of the valve to communicate with the passage-way or channel in the tube or conduit, and an elbow is connected with the shell or casing of the valve to communicate with the passage in the valveplug, to which elbow a supply hose or pipe for the pressure can be attached, and acheckvalve (not shown) can be located in the elbow or otherwise which will permit pressure to enter the receptacle when the liquid is being drawn therefrom and which will shut off the passage of the pressure from the receptacle when the tap is not openfor the withdrawal of liquid.
